20020182046, Dec 5, 2002

Filed:

Apr 10, 2002

Appl. No.:

10/120333

Inventors:

Hagen Schempf - Pittsburgh PA, US
Todd Graham - Pittsburgh PA, US
Robert Fuchs - Pittsburgh PA, US
Christian Gasior - Pittsburgh PA, US

International Classification:

B66F001/00

US Classification:

414/623000

Abstract:

An automated handling system for moving objects from one location to another location is provided with a self-mobile system having a grabber subsystem for grasping objects, including assemblies for movement in four directions, along X, Y and Z axes and through an angle . The system also has a translating carriage assembly for moving the grabber subsystem and power supply and drive systems. A sensing device, such as an imager, is provided to determine the geometric position of the objects and to move the grabber subsystem accordingly. Another embodiment of the system is provided as an accessory to a prime mover. It includes an alignment articulation system, a gross advance system, a tine storage system, a loading head system, and pot grabbers. This automated handling system can be used to move plant containers in nurseries from the ground to a trailer bed and/or from a trailer bed to the ground in a variety of container configurations.

US Classification:

180 91

Abstract:

An easily and quickly reconfigurable robot chassis with at least a pair of forward shafts and a pair of rearward shafts. A wheel is attachable to and removable from each drive shaft. A sprocket is also attachable to and removable from each shaft. A first pair of tracks each extend around opposing forward sprockets and rearward sprockets. A pair of forward track extenders are each removeably attachable to the chassis and each include a forward idler sprocket. A second pair of longer tracks each extend around opposing rearward sprockets, the forward sprockets, and forward idler sprockets. A pair of rearward track extenders are each removeably attachable to the chassis and each include a rearward idler sprocket. A third pair of still longer tracks each extend around opposing rearward idler sprockets, rearward sprockets, forward sprockets, and forward idler sprockets.
